Born on June 16, 1975, in Jackson Heights, New York, Koehler lived in Queens with his divorced mother and three older sisters. He was a popular child model in advertisements, partly because of the red hair he had at the time. As an adult, he graduated from Carnegie Mellon University in Pittsburgh, Pennsylvania, with a degree in theater. He pursued an acting career in 1983, first appearing in Mr. Mom as Alex, in which he was credited by his full name. In 1984, Koehler assumed one of his most well-known roles, appearing as Charles "Chip" Lowell on the TV series Kate & Allie, in which he was also credited by his full name. He then appeared in his second well-known role in 1999, portraying Andrew Schillinger in the TV series Oz.
